UPB Series CNC Bending Machine

The main drive motor adopts servo control technology, achieving an energy-saving rate of over 40% compared with traditional asynchronous motor configurations. The machine frame is optimized through finite element analysis (FEA), delivering superior rigidity and structural strength.

As a standard configuration, the mechanical deflection automatic compensation system effectively eliminates workpiece angle deviations caused by frame and slider deformation during the bending process. Equipped with the German Rexroth full-closed-loop electro-hydraulic servo synchronization control system, the high-frequency valve group ensures rapid response, endowing the machine tool with exceptional stability and precision even under high-speed operation.

An integrated pressure sensor enables stable pressure output, significantly reducing the failure rate of the hydraulic pump. The expanded throat depth, closed height, and slider stroke enhance the machine's adaptability for processing large workpieces.
